The free radical theory of aging asserts that many of the changes that occur as our bodies age are caused by free radicals. Damage to DNA, protein cross-linking and other changes have been attributed to free radicals. Over time, this damage accumulates and causes us to experience aging.
Subsequently, how do free radicals affect skin?
Free radicals are responsible for breaking down our skin’s collagen, resulting in unflattering skin blemishes like wrinkling, dark spots, fine lines and loose, saggy skin.
Regarding this, what are free radicals in beauty?
Free radicals are unstable molecules that damage skin cells. These molecules are missing an electron, so they’re on the hunt. Like a thirsty babe trying to steal your bae, free radicals are looking to steal an electron from stable molecules in order to balance themselves out.

Does exercise increase free radicals?
Moderate exercise is a healthy practice. However, exhaustive exercise generates free radicals. This can be evidenced by increases in lipid peroxidation, glutathione oxidation, and oxidative protein damage. It is well known that activity of cytosolic enzymes in blood plasma is increased after exhaustive exercise.
Can free radical damage be reversed?
